Math Egg Wrap
5, 4, 3
By – Melanie Roberts
Students will explore circumference, measurement, and estimation with an interactive activity.
small blown-up balloon
Skill: Students will determine the circumference of the balloon (by measuring the diameter and using the equation “circumference= D times pi”) and then use that information to estimate how much yarn they will need to go around the balloon x amount of time.
- Students measure diameter of balloon using a centimeter ruler and determine its circumference. Estimate how many times the yarn should be wrapped around the egg to almost cover it up. Cut a piece of yarn that is about that length.
- Dip the yarn into some glue and wrap it around the balloon in a random manner.
- After the glue dries completely, pop the balloon with a pin and carefully pull it out of the egg shape. The egg that remains will look as if it is spun from yarn.
- Tie yarn at the top and hang the eggs in your classroom for decoration prior to Easter.
